• I found this article very useful-thanks. I work as a researcher for a national UK charity and due to budget restrictions I don't have a copy of SPSS and didn't realise that SQL Server had some of these functions.

    David-you seem to have experience with SPSS, how does its 'functionality/ease of use' with these functions compare with that of SQL Server bearing in mind that it is a dedicated analysis suite,

     

    Thanks again
